Multilevel Magnetization Switching in a Dual Spin Valve Structure
Here, we describe a dual spin valve structure with distinct switching fields for two pinned layers. A device with this structure has a staircase of three distinct magnetoresistive states. The multiple resistance states are achieved by controlling the exchange coupling between two ferromagnetic pinned layers and two adjacent antiferromagnetic pinning layers. The maximum magnetoresistance ratio i...
متن کاملFour-state ferroelectric spin-valve
Spin-valves had empowered the giant magnetoresistance (GMR) devices to have memory. The insertion of thin antiferromagnetic (AFM) films allowed two stable magnetic field-induced switchable resistance states persisting in remanence. In this letter, we show that, without the deliberate introduction of such an AFM layer, this functionality is transferred to multiferroic tunnel junctions (MFTJ) all...
متن کاملElectronic structure and bulk spin-valve behavior in Ca3Ru2O7.
Density functional calculations of the fermiology and magnetic properties of Ca3Ru2O7 reveal an unusual state: a bulk spin valve. The ground state consists of nearly half-metallic bilayers stacked antiferromagnetically with a weak coupling. Out of plane transport is very strongly suppressed by the antiferromagnetic alignment, which can be destroyed in favor of ferromagnetism at low energy cost....
متن کاملSpin and Isospin Asymmetry, Equation of State and Neutron Stars
In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.
متن کاملGround State Structure in a Highly Disordered Spin Glass Model
We propose a new Ising spin glass model on Z of Edwards-Anderson type, but with highly disordered coupling magnitudes, in which a greedy algorithm for producing ground states is exact. We find that the procedure for determining (infinite volume) ground states for this model can be related to invasion percolation with the number of ground states identified as 2 , where N = N (d) is the number of...
